What is SCP?
SCP : Self Control Protector It protects a Li-ion battery from the overcurrent and the overvoltage. It has been shipped over 1.5 billion pcs. since its launch in 1993 the beginning of the Li-ion battery commercialization. It is a standard product of the secondary protection device.

What if our SCP will not fit in your application?
Lower current solution In case you would like to use our SCP. However it has to cut under the double rated current In this case you can add a current detection circuit and a resistor. The current detection circuit will detect the lower current and turns the FET on. The SCP can cut at any time you want.
High voltage solution (VDR) Voltage Divide Resistance
High voltage solution (SVS) Suitable Voltage Supply SCP model for 5 cells 2nd-IC will check all the cells FET line for 5 cells. In case of overvoltage: FET turns ON and the suitable voltage will be suplied through the heather
High current solution (Parallel) Parallel Solution
